Préfecture, Mairie, CPAM: Who Handles What?
Find the organisation responsible for the outcome—not simply the nearest counter.
You have a letter, a form and a missing document. Someone suggests the mairie. A website points towards the préfecture. Another person mentions a caisse. It is easy to imagine a single French administration with several interchangeable doors. In practice, the useful question is narrower: which organisation is responsible for the particular thing you need done?
Three names recur in everyday life: the mairie, or town hall; the préfecture, representing the state locally; and the CPAM, a local health-insurance body. They are not three levels of the same customer-service desk. Learning their different roles can save an unnecessary journey—and help you recognise when a helpful adviser is not the person who decides your case.
The mairie: local services and civil records, with important distinctions
A mairie is a familiar starting point for municipal matters, but “ask the town hall” still leaves a crucial question: which town hall? For a birth record concerning a birth in France, the relevant mairie is generally the place of birth, not simply where the person lives now. The procedure also depends on the type of record and who is requesting it. Births abroad follow different routes. Service Public's birth-record guide explains those branches and identifies the request as free.
The distinction matters for someone assembling a file after moving. Their current address does not automatically identify the authority holding every historical record. Start with the document requested, then establish the issuing authority.
French identity cards and passports show another difference: receiving an application is not the same as deciding it. An appropriately equipped mairie records the application and transmits it to the prefectural services; it does not itself decide whether to grant the document. This concerns French identity documents, not an invitation for a foreign national to request a passport from a French town hall. See Service Public's explanation of the mairie's role.
For a practical enquiry, name the service and action: “I need to request this civil-status record” is more useful than “I need to register myself.” The second phrase may conceal several unrelated tasks.

The préfecture: the state's local presence, not a universal walk-in office
The Ministry of the Interior describes the prefect as the state's representative in the department. Prefectural responsibilities extend well beyond individual paperwork, including coordination of state action and public-order functions. A préfecture should therefore not be understood as a larger town hall or a general desk for every public service.
For a person dealing with residence procedures, identifying the responsible authority and identifying the submission channel are separate steps. The official ANEF entry page lists online services including VLS-TS validation, applications concerning certain residence permits, travel documents, naturalisation, work authorisation and changes of address. The word certain matters: do not assume that every situation uses an identical online route.
Use the official guidance for your exact procedure and the relevant local instructions. Check whether the task is online, by appointment or through another specified channel before travelling to a building. A photograph, a map pin or the existence of a reception entrance does not establish that your particular application can be submitted there.
For example, “renewal,” “replacement after loss” and “change of address” may all concern the same residence document but are not interchangeable requests. Describe the event accurately. If a digital form is not working, keep the error and follow the published assistance route; do not assume that sending the same material to an unrelated office creates a valid application.
The CPAM: health-insurance rights and benefits
CPAM stands for caisse primaire d'assurance maladie. The Assurance Maladie network explains that CPAMs manage insured people's affiliation and rights, process healthcare claims and pay relevant benefits. Their work also includes prevention and support for people facing difficulties. They are private-law bodies carrying out a public-service mission—not municipal departments. The same network overview identifies different organisational arrangements in overseas territories and some metropolitan departments, so the local name is not universal. See Assurance Maladie's description of its local bodies.
In everyday terms, separate a question about health-insurance administration from a question about residence permission. An organisation may need evidence issued by another authority without becoming responsible for that authority's decision. A request for a residence-related document in a health-insurance file does not turn the CPAM into an immigration office.
If you have an ameli account, its official services include following reimbursements and certain administrative steps; appointment options depend on the caisse and reason. Consult ameli's account-services guidance. Do not assume that someone who has only just arrived already has account access, or that an account screen alone answers every eligibility question.
This article does not decide whether you qualify for coverage, which scheme applies to you or whether a particular treatment is reimbursable. Those questions require the relevant official process and personal circumstances.

One problem may involve several organisations
Consider a fictional newcomer preparing a health-insurance file while also dealing with residence formalities. They discover that one requested civil-status document is missing.
It is tempting to carry the whole bundle to whichever counter is easiest to reach. A clearer approach is to split the problem into three actions:
- Identify the missing evidence. What exact document is requested, in what form, and by which organisation? Do not substitute a similarly named document without checking.
- Find its issuer. The authority that holds or issues a record may be different from the organisation requesting it.
- Return it through the correct case channel. Preserve the reference number and follow the requesting organisation's instructions.
This is an original organising method, not a universal legal checklist. It helps you see the dependency between tasks without assuming that one institution can complete all of them. If a requirement is unclear, ask the organisation requesting the evidence to specify it before obtaining something unnecessary.
France services can help you navigate, but support is not the decision
A nearby help point may be useful when the difficulty is understanding a digital procedure rather than identifying an entitlement. France services provides free administrative support and access to digital assistance. Its own example makes the boundary concrete: an adviser can help with a French passport or identity-card pre-application on France Titres, but the France services location does not itself renew the document.
Think of assistance as help using the proper route, not a replacement for the organisation responsible for it. Before visiting, check the location's current opening arrangements and explain the task you need help with. Bring the official request or reference you are trying to understand, rather than an unlabelled collection of papers.
Keep control of your personal credentials and sensitive documents. Use the official service or a verified assistance channel, and do not publish identification papers on a public forum to ask which box to tick.
A routing note that fits on one page
For each administrative task, make a short note using the following original prompts:
| Question | What to record | |---|---| | What outcome do I need? | A specific action: request a record, update a detail, follow a reimbursement or submit a named application. | | Who is responsible? | The organisation named in the official procedure, not an assumption based on its address. | | Which branch applies? | Relevant place, document type, status or case category; mark uncertainty explicitly. | | How is it submitted? | The exact official online service, postal route or appointment instruction. | | What already exists? | Case reference, acknowledgement, date sent and any request for additional material. | | What is the next unresolved step? | One question or missing item, with the authority able to answer it. |
Keep separate notes for separate cases. A common personal event—moving, marrying or starting work—can produce more than one administrative task. Do not assume that telling one body has necessarily updated every other record. Use the instructions for each relevant procedure to establish what remains to be done.
Ask a question that can be answered
“I have already done my paperwork” is hard for an adviser to interpret. Try something more precise:
I am trying to complete [named procedure]. I submitted it through [official channel] on [date] and received [reference or acknowledgement]. The remaining question is [specific point]. Is this the correct service for that question?
This wording is a communication aid, not a formal appeal or a substitute for any required form. It distinguishes a new application from an enquiry about an existing one. It also gives the recipient enough context to direct you without requiring you to retell every aspect of your move.
The aim is not to memorise the entire French administrative system. It is to keep four roles distinct: the body responsible, the authority issuing evidence, the channel receiving the file, and the person helping you use it. Sometimes those roles meet in one place. Often they do not. Recognising the difference makes the next step much clearer.
Sources and scope
